Negacionismo, revisionismo e ausência: gênero e sexualidade, em Planos Municipais de Educação do Rio Grande do Sul
Authors: Esquinsani Rosimar Serena Siqueira 
Published: August 2022

O texto discute, circunstancialmente, o tema gênero e sexualidade, em alguns Planos Municipais de Educação sul-rio-grandenses, a partir de uma amostra intencional não probabilística composta por planos de educação dos doze maiores municípios do Rio Grande do Sul. O texto assenta-se em uma pesquisa descritiva, construída a partir de uma metodologia dialética, com procedimento analítico reconstrutivo e pesquisa documental. O texto expõe as menções e ausências dos temas ‘gênero e sexualidade’ nos planos examinados, refletindo, particularmente, sobre os três municípios que tratam o tema com ações que se alinham aos conceitos de negacionismo e revisionismo. Traça cinco argumentos sobre as discussões de gênero e sexualidade na educação básica e, como conclusão, infere: a) a ausência da pauta nos PMEs examinados; b) o caráter alegórico sem efeito prático das menções e, c) o contexto dos movimentos de revisionismo. Tais inferências sugerem que a pauta ‘gênero e sexualidade’ ainda é incipiente em PMEs do estado.

<p><strong>Background.</strong> Soil has variability inherent to how its formation factors interact within the landscape. <strong>Objective.</strong> This study was carried out to describe the variability of some selected physical and chemical soil properties in a 50 years intensively cultivated field. <strong>Methodology.</strong> Eighty soil samples from a 100m × 180m plot were collected at 0 - 25 and 25 – 50cm depths and subjected to physical and chemical analysis. Semivariogram was calculated for each variable to ascertain the degree of spatial variability between neighboring observations. <strong>Results.</strong> Soil pH was moderately acidic with a mean of 5.64 and CV 6.91 % at 0- 25cm while at 25- 50cm it was strongly acidic with mean value of 5.54 and CV 7.04 %. Mean value of OC in the experimental field was higher at the top soil than sub soil with values 5.96 g/kg and 4.54 g/kg respectively with CV 38.26% and 50.44%. At 0 – 25cm, % silt had a significant negative correlation with % sand (-0.790) at 0.01%. % clay and % silt was negatively correlated (-0.428), however CEC was positively correlated with % clay (0.460) at 0.01% probability while OC concentration was positively correlated with TN (<em>r</em> = 0.833) at 0.01. Semivariograms indicated the existence of moderate to strong spatial dependence of soil variables at both depths. <strong>Implications</strong>. The study was used in determining the degradation status of the soils in the area, the findings of this study also showed that spatial structure exist in the soil properties at the field scale in the study site. <strong>Conclusion. </strong>These results support the importance of collecting information in experimental fields to know how a site –specific system should be undertaken.</p>

<p><strong>Background</strong>. Natural cycles and increases in temperature and droughts worldwide are being caused by the climate change effect. In addition, greenhouse gases (GHG) produced by anthropogenic causes are released to atmosphere. In this way, ruminants contribute with 30% of the total methane produced, whereas in Mexico this value represents over 50%. Since droughts are more frequent, production of forage sources which require more water are decreasing alarmingly. Due to the latter, researchers are looking for alternative forages which may alleviate this issue; <em>Opuntia ficus-indica</em> arises as a good forage source. <strong>Objective.</strong> To evaluate the effect of the solid state fermentation (SSF) of prickly pear with yeast cultures on <em>in vitro</em> gas production, ruminal fermentation parameters and <em>in situ</em> degradability. <strong>Methodology.</strong> Three experimental treatments were evaluated: solely prickly pear without previous SSF with yeast cultures (PP) as a control; PP+SC, previously fermented with <em>Saccharomyces cerevisiae</em>; and PP+KM, previously fermented with <em>Kluyveromyces marxianus ITD00262</em>. Treatments were fermented with ruminal liquor and dry matter and protein degradabilities, as well as ruminal fermentation parameters and gas production kinetics were measured. <strong>Results.</strong> The results obtained showed that total degradability of DM increased due to yeast pretreatment (p&lt;0.05). Crude protein degradability and total VFA decreased with PP+SC; however, PP+SC increased total gas production (p&lt;0.05). Otherwise, PP+KM increased propionate production and decreased methane and CO<sub>2</sub> production (p&lt;0.05). <strong>Implications.</strong> The information presented in this research is focused in the use of PP pretreated with yeast strains in order to increase the nutritional value by increasing its protein content. In addition, the presence of yeast cultures in feedstuffs contributes to decrease the methane synthesis in rumen. Additionally, the use of PP in arid and semiarid zones may increase the water availability for ruminants. <strong>Conclusion:</strong> The use of PP pretreated with strains of <em>Kluyveromyces marxianus</em> into livestock feeding increases the protein availability and contributes to a reduction in the <em>in vitro</em> methane synthesis in 23%.</p><p> </p>

Published: August 2022

<p><strong>Background:</strong> The global community has recognized silvopastoral systems (SPS) as an alternative to contribute to the resolution of various socio-environmental problems derived from extensive livestock farming, deforestation, climate change and the current pandemic derived from SARS-CoV-2. Its technical and social viability has motivated various sectors of society to promote its massification or scaling. However, although there are important advances in agroforestry and silvopastoral scientific research in southeastern Mexico, there are no works that address the experiences of massification of silvopastoral systems. <strong>Objective:</strong> The objective of this study was to identify the experiences of massification of various projects of SSP, the participation of social actors and the barriers and trade-offs in their implementation in the state of Chiapas (Mexico). <strong>Methodology</strong>: The study considered an analysis period from 2000 to 2020. A review of scientific and technical documents was made, various social actors were interviewed (livestock producers, technicians from international and national development agencies, technicians and advisers from peasant organizations, technicians from non-governmental organizations, academics from research centers and universities) who have promoted SPS and good livestock practices in Chiapas. Two participatory workshops were held. <strong>Results.</strong> A timeline was built and five relevant experiences of massification of SPS in various agroecological regions of Chiapas were analyzed: a) <em>Scolel Té</em> Project, b) Puyacatengo Agreement (Red Selva), c) Sustainable Rural Development Project in Biological Corridors , d) Innovative mechanisms for a cooperation program towards adaptation to climate change in the Sierra Madre and Costa de Chiapas, e) Early Action Initiatives for Mitigation in livestock areas (IAT-REDD +) and e) Agrosilvopastoral Biodiversity and Livestock Landscapes Project Sustainable (BioPaSOS). Various socio-environmental barriers and alliances between multiple social actors are shown. <strong>Implications:</strong> The work makes a contribution to the historicity of the massification processes of SPS and to the process of change in livestock. It is necessary to continue with an in-depth analysis of the social and technological impact that the various massification initiatives shown have had. <strong>Conclusions</strong>: The massification process that occurred between the years of study has shown the importance of alliances between various social sectors (producers-development agencies-academia-Governments), which has allowed the transition from local projects to projects with broad territorial coverage.</p>
SECUESTRO INORGÁNICO DE CARBONO: LA RUTA OXALATO-CARBONATO EN AMBIENTES KÁRSTICOS CALCÁREOS
Authors: Álvarez-Rivera Oscar , Estrada-Medina Héctor , Jimenez-Osornio Juan José M. 
Published: August 2022

<p><strong>Background.</strong> In recent decades there has been an increase in emissions of carbon dioxide (CO<sub>2</sub>) into the atmosphere, this has caused negative impacts on both natural and anthropic systems. Due to the above, the study of the global dynamics of the carbon cycle has become more important, in order to design technologies and propose management strategies and practices that reduce CO<sub>2</sub> emissions into the atmosphere or remove it from it (carbon sequestration). The removal of atmospheric CO<sub>2</sub> can occur by biotic and abiotic processes and can be deposited in different natural reservoirs both in organic and inorganic form. One of the mechanisms for sequestering carbon in an inorganic way is the oxalate-carbonate pathway (OCP), which deposits secondary carbonates to the soil, from calcium oxalate crystals. <strong>Objective.</strong> A review of inorganic carbon sequestration is carried out, emphasizing the deposition of secondary carbonates in soils through the oxalate-carbonate pathway, and we analyzed its implications in calcareous karst environments.<strong> Main findings. </strong>The OCP has been mainly studied in acid soils, but it could also be important in alkaline soils, since other secondary sources of calcium, such as those carried by the wind, have not yet been considered (i.e. calcium in Sahara desert dust arriving to Yucatan Peninsula annually). <strong>Implications.</strong> The study of the OCP has been intensified in recent years, resulting for us of particular interest in calcareous karst environments, due to its high spatio-temporal dynamics dominated by carbonation-decarbonation reactions. <strong>Conclusion.</strong> Evidence of OCP activity has been found in karst environments; however, this metabolic pathway presents spatial and temporal dynamics, so it is difficult to estimate its contribution to the global dynamics of C, and it may contribute by delaying the return of CO<sub>2</sub> to the atmosphere.</p>

Published: August 2022

<p><strong>Background. Tuberose (</strong><em>Polianthes tuberosa </em>L.)<em> </em>is a native plant of central and southern Mexico, cultivated for cut flower and as for the perfume industry. Farmers propagate it vegetatively, so it is important to generate new varieties by implementing efficient techniques, both to induce mutations and micro-propagation. <strong>Objective. </strong>Establish the protocol for the <em>in vitro</em> propagation of <em>P. tuberosa </em>L. from foliar and flower tissue. <strong>Methodology. </strong>Leaf<strong> </strong>and button explants were placed on the surface of the culture medium base GC, containing inorganic salts Murashige and Skoog (1962) per liter, coconut water 50 mL L<sup>-1</sup>, 20 g L<sup>-1 </sup>of sucrose, 6.4 g L<sup>-1 </sup>of agar, being the pH adjusted to 5.7. With this basic medium were prepared a series of culture media containing benzylaminopurine (BAP) , naphthaleneacetic acid (ANA), 2,4-dichlorophenoxyacetic acid (2,4-D), indole acetic acid (IAA) and kinetin. <strong>Results. </strong>Shoot regeneration (3.5 %) was solely from button tissue explants on solid media containing BAP and ANA; media T1 (1.1 %), T3 (3.5 %) and T11 (2.5 %). The shoots developed roots in the medium with indolbutiric acid (1 mg L<sup>-1</sup>) and BAP (0.1 mg L<sup>-1</sup>). In foliar tissue cultures, the regeneration of green callus was achieved in a higher percentage (50.9 %) in the solid media with BAP (4.5 mg L<sup>-1</sup>) and ANA (0.05 mg L<sup>-1</sup>) and sucrose 20 g L<sup>-1</sup>. <strong>Implications.</strong> The protocol was developed that allowed obtaining tuberose seedlings from flower buds. This attributes to the <em>in vitro</em> conservation of germplasm, and initiating genetic improvement programs for <em>P. tuberosa</em> with new and desirable characteristics, to increase biodiversity in the crop. <strong>Conclusions.</strong> Both shoot induction and development were observed in media containing BAP (4.5 mg L<sup>-1</sup>) and ANA (0.1 mg L<sup>-1</sup>). .</p>

Published: August 2022

<p><strong>Background: </strong>Hydroponic Green Fodder (HGF) is a technology that allows the efficient production of fresh forage with a high protein content. <strong>Objective:</strong> To analyze the bromatological and productive variables of HGF with four native maize varieties located in the southern region of the state of Veracruz, Mexico. <strong>Methodology: </strong>Bromatological and productive parameters of four varieties of native corn (V1= Soteapan white, V2 = Tulín white, V3 = Mecayapan yellow, V4 = Cosoleacaque white) were analyzed in Acayucan, Veracruz. The productive variables evaluated were height, biomass and potential yield (Py)], while the bromatological were: Dry Matter (DM), Ash (A), Crude Protein (CP), Crude Fiber (CF) and Ethereal Extract (EE), the relationship between the dry weight of the seed (ws) and Py was also analyzed. The experimental design was completely randomized with three replications, using 200 g<sup>-1</sup> of seed of each variety placed in germination trays of 30 cm<sup>-2</sup>, using a nebulization system of 6.6 to 7.2 L h<sup>-1</sup> and an irrigation frequency of two minutes every four hours. The variables were analyzed with the Tukey test using SAS University Edition software and Pearson's linear correlation was used to determine the relationship between ws and Py. <strong>Results:</strong> V1 was the best variety in height (34.3 cm<sup>-1</sup>), Py (21.5 kg m<sup>-2</sup>) and PC (22.13%), with 29% more roots and correlating with heavier seeds. <strong>Implications:</strong> The study was carried out with a nebulization system with a higher frequency of irrigation, since it was carried out in the months of May-June, with temperatures above the average. Therefore, it is necessary to adjust the irrigation time according to the environmental conditions. <strong>Conclusion:</strong> It is concluded that the native varieties V1 and V2 have a high potential for the production of HGF.</p>

<p><strong>Background</strong>. Eighty percent of beef produced in Mexico is consumed domestically. However, in recent years <em>per capita</em> domestic consumption has gradually decreased. Identifying consumer preferences and their perspectives on beef quality could provide information for the design of programs focused on the improvement of beef production chain and encourage meat consumption. <strong>Objective</strong>. In this study the definition of quality is provided and discussed and the published evidence on the main attributes considered by the Mexican consumer at the time of beef purchase are revised, providing a critical perspective on beef quality appreciation and to identify some implications and limitations. <strong>Methodology. </strong>Was performed<strong> </strong>a bibliographic search of available literature including the Mexican consumer perspective on beef quality attributes published in peer reviewed papers from international and national indexed journals. <strong>Main findings.</strong> Evidences on the main criterions that Mexican consumer considers as indicators for beef quality during de beef purchase are presented, and some implications and perspectives for the future adoption of more complex systems to guarantee beef quality and add value to the entire production chain are discussed. <strong>Implications</strong>. This study provide some directions on the establishment of proposals to adequately define the Mexican beef consumer preferences focused on quality and consistency of product, favorable for the whole beef industry. <strong>Conclusions</strong>: The price of beef was identified as the main criterion considered for Mexican consumer for purchasing of beef, and secondarily, his perspective include intrinsic attributes generically describing the beef quality. More studies are necessary for the identification of factors affecting the beef consistency and to adequately define the most important attributes that satisfy the Mexican consumer perspective on beef quality.</p>

<p><strong>Background.</strong> In mixed crop livestock farming systems in Ethiopia, sorghum stover and other crop residues are a strategic livestock feed resource. Farmer’s decisions and intensity of use of sorghum stover for feed than other uses are closely associated with biophysical and socioeconomic characteristics. <strong>Objective.</strong> This study explores determinants of sorghum biomass uses for livestock feed in three major sorghum growing agroecological zones of Ethiopia. <strong>Methodology.</strong> Tobit and double hurdle models were run and likelihood ratio test was performed to select most suitable estimation technique. <strong>Result.</strong> Allocation of sorghum stover for feed showed a significant association with sorghum growing agro-ecological zones, highest in the lowland (86.73%) and the lowest in highland sorghum growing agroecological area (61.75%). Econometric model result revealed that among other factors; availability of feed from grazing and other crop residues had a negative effect on decision to use and intensity of use of sorghum stover for feed. Household’s livestock ownership and family size had positive effects. <strong>Implication.</strong> Decision variables influenced household’s decision and intensity on use of sorghum stover for feed at three major sorghum growing zone differently. <strong>Conclusion.</strong> Knowledge generated through this study may help any research and development efforts to enhance productivity of sorghum biomass for livestock feed and livestock improvement strategies.</p><p><strong>Keywords</strong>: Agroecology; Crop residue; Econometric models; Feed resources; Sorghum stover.</p><p><strong>Keywords</strong>: Agroecology; Crop residue; Econometric models; Feed resources; Sorghum stover.</p>
ASSESSMENT OF SOIL MOISTURE AND NUTRIENTS ON TERRACE SLOPE OF HARD-SETTING SOILS IN SEMI-ARID EASTERN KEN
Authors: Njiru Emerita Ndwiga , Baaru Mary , Gachene Charles 
Published: August 2022

<p><strong>Background:</strong> Terraces are structures consisting of ditches and embankments used to control erosion and increase land productivity. There is, however, little emphasis on the effects of the ditch dimensions on soil moisture and nutrient dynamics. <strong>Objective:</strong> To determine the effect of varying ditch depths on soil moisture and nutrient quantities and their variability within the terrace slope on hard-setting soils. <strong>Methodology:</strong> Soil samples were collected seasonally in 2014 and 2015 from terraces with different ditch depths (60, 30, and 0 [control] cm) for the determination of soil moisture content (SMC). The samples were collected from the upper, middle and lower slope positions of each terrace. Soil from the three slope positions of each terrace was also sampled at the end of the study and analyzed for total nitrogen (%TN), available phosphorous (Av. P), exchangeable potassium (K<sup>+</sup>) and % organic carbon (OC) contents. Data were subjected to a two-way analysis of variance and differences in means determined at a 95% level of confidence. <strong>Results:</strong> Significant interactions (P&lt;0.001) in SMC were observed between seasons, ditch depths and slope positions. Higher SMC was found in treatments with 30 and 60 cm ditch depths in all the slope positions and seasons compared to the control. Soil moisture contents in the lower and upper slope positions were significantly different between the terraces with 30 and 60 cm ditch depths when rainfall was high and evenly distributed, but non-significant in poorly distributed rainfall seasons. Significant differences (P ≤ 0.05) in contents of total nitrogen and available phosphorous were found between the upper and lower slope positions of the terraces with ditches. <strong>Implications: </strong>The effect of ditch depths on moisture, total nitrogen and available phosphorous contents and their variability within the slope depended on the amount and distribution of rainfall. <strong>Conclusion: </strong>Construction of terraces with shallow ditch depths (of 30 cm) is recommended to conserve soil moisture and nutrients nitrogen and phosphorous on hard-setting soils in the marginal areas of semi-arid Eastern Kenya. </p>
