Ordinary Portland cement is a major construction material worldwide. Cement manufacturing industry is one of the carbon dioxides emitting sources besides deforestation and burning of fossil fuels. The global warming is caused by the emission of greenhouse gases, such as CO2, to the atmosphere. Among the greenhouse gases, CO2 contributes about 65% of global warming. The cement sector accounts for around 7% of worldwide greenhouse gas emissions of the earth’s atmosphere. In order to address environmental effects associated with Portland cement, Alternative binders for concrete production are needed. Low-calcium (Class F) fly ash-based geopolymer from Vijayawada was used in this study. Geopolymer concrete was made with the help of a thermal power plant. The combination of sodium silicate solution and sodium hydroxide solution was used as alkaline solution for fly ash activation. Alkaline solution to fly ash ratio was varied as 0.45. The concentration of sodium hydroxide solution was maintained as 8M, 10M & 12M (Molars). The curing condition of geopolymer concrete was varied as ambient curing. The compressive strength, Split Tensile Strength of the geopolymer concrete was tested at various ages such as 7 and 28days. From the test results it was found that as the alkaline solution to fly ash ratio increases, the strength of geopolymer concrete also increases.

Published: June 2022

• Shear on beam is defined as the internal shear stress of a beam caused by the shear force applied to the beam.
• The fiber reinforced polymer (FRP) has arisen as a promising material for shear strengthening of RCC structures due to their superior qualities such as high specific strength, better fatigue and chemical resistance.
• This resistance to sliding or resistance to forces that are parallel to the beam surface, generates a shear stress within the material.
• Basalt fiber has possessed high tensile strength, better chemical and heat resistance which is higher than that of steel fiber.
• The study finds that the beams strengthened with and without BFRP (basalt fiber reinforced polymer) strips fails in shear for L/d ratio 2.5 and the enhancement of the shear capacity of strengthened beams ranges from 5 % to 20 %.

The Arms and Armour of Titian’s Allegory of Marriage
Authors: Watts Karen
Published: June 2022

This chapter demonstrates that a technical study of the arms and armour depicted in paintings can be a useful tool in iconographic interpretation. The armour in Titian’s paintings—especially those of two of his commissioners, Alfonso d’Avalos and Francesco Maria I della Rovere—can reveal how patrons wished to be understood in a military capacity. The armour presented can also be shown to reference Roman as well as medieval topoi. A secondary theme is an analysis of the allegorical role of the Cupid figure. It is not possible to affirm the identity of the sitter in the Allegory, but a close look at Titian’s armoured portraits and the military metaphors may lead to a better understanding of the painting.
Psyche, Venus, Ceres and Their Friends: Titian’s Remixes
Authors: Joannides Paul
Published: June 2022

The composition of Titian’s Allegory of Marriage fused two earlier designs: his own Venus Withholding Cupid’s Weapons, drawn on the original canvas, and Giulio Romano’s Psyche before Proserpine. Titian reworked this fusion in a lost Psyche before Venus, probably painted in the 1530s but first documented in 1550. This much-copied picture was itself adapted, with various changes of cast and emphasis, by Titian and his studio. Towards 1560 Titian extended the composition horizontally in Venus Blindfolding Eros (Washington), now severely truncated, but whose full composition exists in the underlayers of Galleria Borghese’s famous painting which, on its surface, was modified to show the Blindfolding of Cupid, not now by Venus, but by Diana, rejecting love for the hunt.
Art and the Double Meaning of Reflection in Titian’s Allegory of Marriage
Authors: Unger Daniel M.
Published: June 2022

A small yet significant detail in Titian’s Allegory of Marriage may add new dimension to what still remains an ambiguous painting. It relates to the crystal orb, which Titian rendered as a mirror, where one can discern a blurred reflection of a person. The orb loses its transparent nature, the image concealing what should have been seen behind it. This detail, complemented by additional reflections of two female figures on both sides of the warrior’s armour, are at the core of this chapter. They accent an interconnectivity alluding to a sophisticated visual expression of the intellectual roles of the painter and his viewer. With his rendition of this orb, Titian was emphasizing the dual meaning of the word ‘reflection’ (riflessione).
Titian’s Allegory of Marriage as an ‘Allegory of Peace’
Authors: Benninga Sara
Published: June 2022

This chapter interprets Titian’s painting as an allegory of peace, integrating the mythological account of Mars and Venus with a political symbol of balance, as represented by the sphere held by the female protagonist. The mythological story of the love affair of Mars and Venus as told by Lucretius, Statius, and Plutarch, and the visual representations that followed this tradition are discussed as the sources for Titian’s painting. Contrary to previous readings of the glass sphere as a symbol of transience or inconsistency, it is discussed here as a sign of balance in relation to an iconographical precedent. This new reading of Titian’s Allegory is strengthened by the consideration of its influence on successive allegorical paintings of peace.
Vision and Touch in the Allegory of Marriage
Authors: Lehman Geoff
Published: June 2022

Titian’s Allegory of Marriage depicts an equivocal moment of intimacy through a network of visual and tactile interactions. This dialectic of touch and vision evokes a range of embodied experiences that, through empathetic identification, also implicate the viewer and define a phenomenology of viewer response. Furthermore, the interplay of optical and haptic values invokes Titian’s painterly practice itself, mediating between the picture as window and the brushstroke as touch. The interpretive possibilities of this dialectic culminate in the crystal sphere, a discrete object receptive to human touch that also relates abstractly to the scattering of light in space, suggesting a more radical phenomenology of intimacy that transcends the limitations of bodily Gestalt and the separation between picture and viewer alike.

In today's business world, in fact many agreements and business activities are found that contain elements that are unfair to parties whose economic or social status is weaker under the pretext of maintaining fair business competition. state intervention is required through the establishment of a legal protection system for consumers. The problems studied are how the action of determining the price of anchovy is carried out by business actors to consumers and how is the legal protection for consumers against setting the price of anchovy (a case study on the sambu market). The research method used is a normative juridical research method and is supported by primary data. Indirect evidence that occurs in the sambu market carried out by anchovy business actors and anchovy competitor business actors occurs indirectly with communication that indirectly states an agreement. KPPU does not supervise the sambu market because there is no direct evidence. Agreements between anchovy business actors are carried out separately and at different times and there is no evidence that there have been direct or indirect meetings or discussions by business actors. There are 2 (two) forms of legal protection, namely, preventive legal protection with socialization which aims to create consumers and business actors who are smart and aware of their rights and obligations, and repressive legal protection by resolving disputes that occur with sanctions in the form of fines or settlements. in general court.
EFFECT OF MANAGERIAL SKILLS ON THE DEVELOPMENT OF DAIRY COOPERATIVES IN KIAMBU COUNTY
Authors: Mugwe Peter Githinji
Published: June 2022

Cooperatives societies are part and parcel of an increasing number of people in formal and informal employment the world over. The study sought to examine how managerial skills affect the development of Dairy Cooperatives in Kiambu County. Grounded on the Social Capital and Resource-Based Theory, this study adopted the descriptive research design. In this study, the target population was 59,635 registered Dairy Cooperative members while the sample size was 398 respondents who were picked via stratified random sampling. Data collection involved questionnaires that contained 5-point scale Likert-type statements. Descriptive and inferential statistics were carried out. In this case, tests such as central tendency (mean), frequencies, percentages, and standard deviation in addition to Pearson and regression analysis were utilized. The findings show that managerial skills had a significant influence on the development of dairy cooperatives. This is evidenced by a positive and statistically significant relationship between managerial skills & leadership (r=.156, p<0.001) and the development of dairy cooperatives. These findings lead to the conclusion that the kind of managerial skills and leadership in dairy cooperatives affected their development. The skills deployed by the managerial team would thus determine the level of development in dairy cooperatives. As such, there was a need for dairy Cooperatives to have robust management teams staffed with highly competent and experienced managers. The integrity of the firms should be established and regularly assessed to avoid corruption and mismanagement of the finances. Training is also necessary to enhance the capacity of managers and employees. This could be done in-house or sponsored by institutions of learning.
A global inventory of quantitative documentary evidence related to climate since the 15th century
Authors: Burgdorf Angela-Maria
Published: June 2022

Abstract. Climatic variations have impacted societies since the very
beginning of human history. In order to keep track of climatic changes over
time, humans have thus often closely monitored the weather and
natural phenomena influencing everyday life. Resulting documentary evidence
from archives of societies enables invaluable insights into the past climate
beyond the timescale of instrumental and early instrumental measurements.
This information complements other proxies from archives of nature, such as
tree rings in climate reconstructions, as documentary evidence often covers
seasons (e.g., winter) and regions (e.g., Africa, eastern Russia,
Siberia, China) that are not well covered with natural proxies. While a
mature body of research on detecting climate signals from historical
documents exists, the large majority of studies is confined to a local or
regional scale and thus lacks a global perspective. Moreover, many studies
from before the 1980s have not made the transition into the digital age and
hence are essentially forgotten. Here, I attempt to compile the first-ever
systematic global inventory of quantitative documentary evidence related to
climate extending back to the Late Medieval Period. It combines information
on past climate from all around the world, retrieved from many studies of
documentary (i.e., written) sources. Historical evidence ranges from personal
diaries, chronicles, and administrative and clerical documents to ship logbooks and
newspaper articles. They include records of many sorts, e.g., tithe
records, rogation ceremonies, extreme events like droughts and floods, and weather and phenological observations. The inventory, published as
an electronic Supplement, is comprised of detailed event chronologies, time
series, proxy indices, and calibrated reconstructions, with the majority of
the documentary records providing indications on past temperature and
precipitation anomalies. The overall focus is on document-based time series
with significant potential for climate reconstruction. For each of the
almost 700 records, extensive meta-information and directions to the data
(if available) are given. To highlight the potential of documentary data for
climate science, three case studies are presented and evaluated with
different global reanalysis products. This comprehensive inventory promotes the first ever global perspective on
quantitative documentary climate records and thus lays the foundation for
incorporating documentary evidence into climate reconstruction on a global
scale, complementing (early) instrumental measurements and natural
climate proxies.

Abstract. Climate warming and the resulting acceleration of freshwater
discharge from the Greenland Ice Sheet are impacting Arctic marine coastal
ecosystems, with implications for their biological productivity. To
accurately project the future of coastal ecosystems and place recent trends
into perspective, palaeo-records are essential. Here, we show runoff
estimates from the late 19th century to the present day for a large
sub-Arctic fjord system (Nuup Kangerlua, southwest Greenland) influenced by
both marine- and land-terminating glaciers. We followed a multiproxy
approach to reconstruct spatial and temporal trends in primary production
from four sediment core records, including diatom fluxes and assemblage
composition changes and biogeochemical and sedimentological proxies (total
organic carbon, nitrogen, C/N ratio, biogenic silica, δ13C,
δ15N, and grain-size distribution). We show that an abrupt
increase in freshwater runoff in the mid-1990s was reflected by a 3-fold
increase in biogenic silica fluxes in the glacier-proximal area of the
fjord. In addition to increased productivity, freshwater runoff modulates
the diatom assemblages and drives the dynamics and magnitude of the diatom
spring bloom. Our records indicate that marine productivity is higher today
than it has been at any point since the late 19th century and suggest
that increased mass loss of the Greenland Ice Sheet may continue promoting
high productivity levels at sites proximal to marine-terminating glaciers.
We highlight the importance of palaeo-records in offering a unique temporal
perspective on ice–ocean–ecosystem responses to climate forcing beyond
existing remote sensing or monitoring time series.
A study of preservice teachers’ attitudes toward their role as students of statistics and implications for future professional development in statistics
Authors:   California State University Fullerton, Lancaster Stephen
Published: June 2022

I analyze data from the attitudes of 56 preservice primary teachers related to their role as continuing students of statistics. The variables investigated include preservice primary teachers’ (1) attitudes toward future professional development in statistics, (2) current knowledge of statistics, (3) current statistical self-efficacy, and (4) current self-efficacy to learn statistics in the future. My results suggest that (1) current self-efficacy to learn statistics in the future is a moderate predictor of preservice primary teacher beliefs that future professional development in statistics will help their classroom teaching, and (2) current self-efficacy to learn statistics in the future can vary for preservice primary teachers throughout their preparation program.

Conceptions of distribution held by middle school students and preservice teachers
Authors:   Eastern Washington University, Canada Daniel
Published: June 2022

This paper examines how preservice teachers and middle school students reason about distributions as they consider graphs of two data sets having identical means but different spreads. Results show that while both subject groups reasoned about the task using the aspects of average and variation, relatively more preservice teachers than middle school students combined both aspects to constitute an emerging form of distributional reasoning in their responses. Moreover, these emergent distributional reasoners were more likely to see the data sets as fundamentally different despite the identical means used in the task.

Authors: Sekarsari Meira , Dwiatmoko Hermanto
Published: June 2022

Mode choice of transportation is a transportation planning process that functions in determining travel expenses or can be interpreted as an effort to separate people’s travel to understand the relationship between modes and a factor that influences the choice of other modes. This study aims to determine the mode choice of public transportation and the probability of using the Tayo Bus and City Transportation in Tangerang City. The research approach used is quantitative with primary data sources obtained from closed questionnaire instruments with stated preference techniques for 50 respondents using the Tayo Bus on the Ciledug-TangCity route and 50 respondents using the City Transportation for the Ciledug- Cikokol route. The analysis of mode choice uses the binomial logit model with attribute variables in the form of changes in travel costs, changes in travel time, and changes in headway. The results of the analysis show that the probability of mode choice for the changes in these attributes is 92.107% or Tayo Bus and 7.893% for City Transportation. The main factor that underlies the opportunity to choose the Tayo Bus is the cheaper cost than City Transportation, while the opportunity for choosing City Transportation the ease of access felt by passengers. Changes in the attributes of travel costs in both modes are increased or decreased, passengers generally prefer to use the Tayo Bus. Likewise with the attributes of travel time and headway, although it is increased or decreased, passengers tend to prefer to use the Tayo Bus as a mode to get their destination

Keywords: mode choice, stated preference, and binomial logit model.

Research questions were answered using mean and standard deviation. Hypotheses were tested using Analysis of Variance (ANOVA). Major findings of the study showed that the experimental group achieved higher and retained more mathematical concepts than their counterparts in the control group. It is therefore recommended that teaching mathematics strictly in English should be de-emphasis to enable the mathematics teachers to explain in the mother tongue whenever they are teaching. Also, curriculum developers should take into consideration the language interference between English and the language of the environment in their planning for junior secondary school students.

Published: June 2022

The capability to record events of different magnitude at various epicentral distances (magnitude sensitivity of the station) was studied basing on representative statistical material ontained by the results of Karatayu seismic array operation for more than 10 years period. The dependence of magnitude sensitivity on azimuth of seismic waves arrival was studied. It is shown that depending on the direction, the station has different capabilities in recoding of small earthquakes at the same distance. The examples of small events recorded by Karatayu station are shown by a series of two explosions of shells at military warehouses in the south Kazakhstan in 2019 and 2021.

What Demotivates EFL Learners
Authors: Wu Yanting , Ding Feng
Published: June 2022

70 university EFL learners of low proficiency were surveyed to investigate the demotivating factors in learning English as a foreign language (EFL) in China, and the ebb and flow of enthusiasm towards English experienced by EFL learners of low proficiency. Findings from this study indicate that less-proficient EFL learners might go through four stages of emotion, from motivated to demotivated, to remotivated, and lastly to relinquish. Burdensome coursework, persistent negative feedback, and disagreeable teachers are the three main factors that affect students’ enthusiasm for learning English. The implications of this study are that it complements the studies of demotivators by examining the causes of less proficient students’ fluctuation of enthusiasm for English in the Chinese context, and further explores the processes by which learners’ enthusiasm for English changes, so that policymakers and administrators can identify and address problematic aspects of educational policies and classroom practices.
Bonding Through Contexts: Herstories Retold on YiXi Talks
Authors: Wan Rong
Published: June 2022

No man is an island, which explains the necessity of zooming into the processes of social bonding and interactive alignment taking place between the speaker and the addressee. Therefore, this study incorporates the emerging notion of “bonding” (Ide and Hata 2020) into the extensively explored concept of “context”, in the hope of shedding light on social relationships that arise from public speakers and the audience in Chinese public speeches. Specifically, through the lens of the stories of marginal women stories narrated in YiXi Talks (the Chinese counterpart of TED), this study not only aims at the investigation of bonding effect achieved in public speeches. But more importantly, it attempts to bravely voice for women’s hardships and predicament, demonstrate their constant struggles and resistance against social inequalities and call for due attention and support to marginal women in China and beyond.

De indígenas a campesinos
Authors: Landa Mariano Báez
Published: June 2022

Este artículo busca exponer y discutir los cambios paradigmáticos que experimentó la antropología mexicana en su enfoque sobre los pueblos indios y sus miembros, específicamente las transformaciones en los cuerpos teóricos y los discursos de antropólogas y antropólogos en México respecto a los sujetos del mundo rural, especialmente el gran viraje experimentado durante las décadas 1970-1980, donde el corpus teórico y práctico de Gonzalo Aguirre Beltrán fue sustituido por los paradigmas marxista y del dependentismo marginalista, tanto en los espacios de la academia como en las políticas públicas. El concepto antropológico de indio o indígena fue sustituido por el económico-sociológico de campesino habitante de áreas deprimidas y marginadas, reflejando poderosamente la influencia de paradigmas provenientes de la sociología, la economía agrícola y la salud pública sanitarista que intervinieron en el diseño y aplicación de acciones asistenciales hacia el medio indígena a partir de los años setenta. Los indios mexicanos renunciaron en muchos casos a, o les fue negada, su condición etnológica de población étnica y culturalmente diferenciada, teniendo que adoptar la condición sociológica de campesinos pobres y marginados, como una estrategia de interlocución con el poder gubernamental y sus agencias de asistencia, para intentar recuperar la tierra o alcanzar beneficios que ofrecían las políticas de compensación social. Será la rebelión zapatista, protagonizada por indios mayas en el estado de Chiapas en el sureste mexicano, lo que logre reposicionar a los pueblos indios en su condición étnica y cultural frente al Estado y a la propia antropología.
Los Mapuche de Chile
Authors: Soto Elba
Published: June 2022

Los mapuche de Chile son considerados “ciudadanos nacionales” y la historia muestra que el Estado ha buscado “integrarlos”, en la lógica de la igualdad. El objetivo de este artículo es comprender la forma en que los mapuche se significan con relación al Estado y a la sociedad chilena. Nuestra análisis de los discursos de los mapuche mostró que, pese a los intentos de asimilación, ellos se identifican como “un otro”, no como un chileno más. Esta tesis fue realizada en la Facultad de Educación de la Universidad Estadual de Campinas (Unicamp), con beca de la Fundación de Apoyo a la Pesquisa del Estado de São Paulo (Fapesp) y en colaboración con los mapuche del Área de Desarrollo Indígena del Lago Lleu-Lleu, VIII Región de Chile.

Published: June 2022

This study was conducted to evaluate the possibility of increasing Bradyrhizobium efficiency in fixing biological nitrogen in soil. Bradyrhizobium isolates were obtained from cowpea field in certain Iraqi provinces. Isolates were purified, propagated and authenticated. Isolates were then subjected to a range of Gamma ray dose of irradiation of 0 to 800 Gy. For all isolates number of nodules formed by all isolates increased with the increase of Irradiation dose to 400 Gy after which numbers of nodules of all isolates were markedly reduced. Highest nodules numbers of all isolates were observed under 400 GY irradiation dose. Under the same irradiation dose of 400 GY numbers of nodules differ with different isolates being the highest under isolate No. 2.
