Multivariable Analysis and Phenotypic Diversity Studied for Some Barley Genotypes under Heat Stress
Full text linkHeat stress is one of most domineering abiotic stress influences that border barley production.� Herein, three different field screening locations were carried out at Sakha, Mallawi and New-valley research stations, to identify the response of ten barley genotypes to different temperatures degrees using phenotypic diversity and, multivariable analysis during two consecutive seasons 2020/2021 and 2021/2022 under different temperatures degrees. Heat stress index (HI) activated a reduction in all traits ranged from lowest average reduction in plant height PH by (5.43 and 20.37%) to highest average reduction in no. of tillers /m2TM by (14.49 and 40.83 %) under Malawi (T2) and New Valley (T3) locations respectively as camper by Sakha, also high temperature enhancement all the genotypes to quicken flowering and days to maturity by average (7.24 and 8.35 %) under New Valley. Days to heading HD �and to maturity MD �exhibited a strong and significant negative relationship with all studied traits Loading principal component analysis PCA accounted 86.1% of the total variability, which PCA2 clarified 24.2 % of the total variability influenced by HD and MD which placed in the left side (negative). Scatter plot of PCA categorizing all the barley genotypes in four groups ��indicated that the Egyptian barley genotypes (Giza 137, Giza 138, line5, line 1 and line 3) were separate from the other genotypes and ��located in the right side with of PCA1 analysis cluster with a significant distance which could be considered as a heat tolerance genotypes. A cluster heatmap �according their resulted form all studied traits ��showing that the ten barley genotypes were clustered into two main clusters, Giza 137, Giza 138, line5, line 1 and line 3 were the most closed genotypes together due to their tolerance to heat stress while line 2 and line 8 were the most closed genotypes together due to their sensitive to heat stress. Thus, we could use them as a source for future barley breeding programs for heat stress such as important step to get a new genotype with high heat tolerance and high yield
Exploration of Dunalliella Salina Culture from the Colorada Lagoon in Photobioreactors as Biotechnological Perspectives: Potentialities and Applications
Full text linkMicroalgae are resources with several scientific and industrial uses, under this framework, the study aims to explore the possibility of taking advantage of the microalgae present in saline lagoons in southern Bolivia to obtain microalgae rich in ?-carotene. The microalgae samples were cultured in Erlemeyer flasks with Ben-Amostz Avron culture medium, by successive tests the Dunaliella salina was separated, later this inoculum was cultured in a 5-liter photobioreactor, then in 90 liters until reaching 140 liters culture using macronutrients and artificial light 20000 lux, it was possible to obtain microalgae composed of the Dunaliella salina known as the green phase, whose average cell density is 113929 cell/ml. From this phase, carotenogenic induction of the microalgae was carried out with the removal of nitrogen and phosphorus in the culture medium, the average content of ?- carotene in the red phase biomass was 12 mg/Li equivalent to 890 mg/100 g, and the conversion was 4.8 g ?-carotene/g chlorophyll, which contrasts with the fact that biomass contains a higher percentage ?-carotene. In the same way, it was possible to obtain biomass in the red phase by carotenogenic induction using natural light with 100000 lux maximum daily, the ?-carotene content was 4.26 mg/Li. This shows the feasibility of obtaining biomass rich in ?-carotene with natural light and macronutrients

Stop Bullying-A University Theatre Project (Pilot) Implemented in a Summer Camp for Children and Designed to Promote Social Cohesion
Full text linkThis study explores the Stop Bullying theatre initiative, implemented as part of a summer camp program designed to promote literacy and social cohesion through participatory drama. Grounded in a Design-Based Research framework, the project engaged 13 children (aged 8�12) in reading, rehearsing, and staging Claudia Kumpfe�s play Alone! School as a Crime Scene!, which addresses bullying and peer dynamics between childrenin schools. A variety of methods were employed, including pre- and post-intervention surveys on bullying and social cohesion, daily field diaries from theatre coaches, and qualitative feedback from children and parents. The results demonstrate statistically significant improvements in the participants� sense of equality, comfort, and group belonging, supported by qualitative accounts of empathy, cooperation, and new friendships. Coaches� observations indicated increased fluency, motivation, and expressive oral reading. The findings highlight theatre pedagogy�s potential to foster inclusion, solidarity, and democratic participation while also offering low-threshold entry points for literacy engagement. This study underscores the value of integrating socially relevant themes into participatory arts projects to cultivate both cognitive and socio-emotional development in inclusive educational settings
An Empirical Study on Green Consumerism among College Students of Mumbai with Respect to Electric Vehicles
Full text linkThis study investigates the attitudes, perceptions, and purchase intentions towards electric vehicles (EVs) among college students in Mumbai, a demographic crucial to the future of sustainable consumption. A quantitative approach was employed, utilizing a structured questionnaire distributed to a sample of 312 students across various colleges in Mumbai. The findings reveal a strong environmental consciousness (Mean=4.42) and a positive attitude towards EVs as a symbol of modernity (Mean=4.05). However, a significant intention-behavior gap exists. The primary barriers to adoption are high purchase cost (72.1%), perceived lack of charging infrastructure (68.3%), and range anxiety (55.4%). While government subsidies are seen as a key motivator (65.7%), awareness of existing policies remains moderate. The study concludes that while Mumbai\u27s youth are ideologically aligned with green consumerism, practical and economic barriers hinder the translation of intention into purchase behavior. Recommendations include enhanced policy communication, targeted educational campaigns, and infrastructure development focused on academic institutions
Quality of Employment: Intergenerational Labor Precariousness from the Perspective of the IMCE in Santa Cruz De La Sierra 2023 – 2025
Full text linkThis study evaluates the Quality of Employment (QoE) and analyzes intergenerational labor precariousness in Santa Cruz de la Sierra, Bolivia, during the 2023�2025 period. The conceptual framework is based on the Theory of Segmented Labor Markets (SLMT), focusing on the unequal insertion of different generational cohorts. A quantitative approach was adopted, using the Multidimensional Quality of Employment Index (IMCE), which is grounded in the Alkire-Foster (AF) double-threshold model. The IMCE assesses deprivation across three main dimensions: Labor Income, Labor Stability, and Employment Conditions. The poverty line for poor quality employment was set at K = 50%. The results are based on a representative sample of 415 employed workers (ages 18�65). Findings confirm that the overall QoE remains considerably low (IMCE2025= 0.45) and below the historical Bolivian national average (0.47). The Headcount Ratio of Poor-Quality Employment (H) reached 68%. The intergenerational analysis confirms labor market segmentation: Generation Z exhibits the highest vulnerability (IMCEZ = 0.37), validating its predominant insertion into the secondary sector. Youth precariousness is highlighted by high contractual instability (27% without a formal contract) and lack of social protection (68% without access to benefits). Gender disparity is acute: Generation Z females show the lowest IMCE (0.36) and an incidence rate of 92% (H), implying that almost all young employed women face poor quality employment. The structural challenge facing the labor market is fundamentally the quality of employment, not merely access. Urgent public policy intervention is required to strengthen contractual stability and social protection mechanisms to promote Decent Work, particularly for highly vulnerable groups like Generation Z women

The Study of the Complexity and Capacity of Urban Floristic Diversity in Arid Zones, Exemplified by the City of Bukhara, RUz
Full text linkThis study investigates the biodiversity of urban flora in the arid zone of Bukhara, Republic of Uzbekistan. The research is based on newly proposed methods�examining the complexity and potential of flora biodiversity. Additionally, the study employs the biodiversity index, which includes species abundance equalization (the probability of species occurrence) and the Shannon index. This work represents the first attempt to calculate biodiversity complexity and potential indicators for real ecological systems.
The findings indicate that the biodiversity of Bukhara\u27s urban flora is characterized by uneven species abundance. A few tree species (Pinus brutia var. eldarica (Medw.) Silba; Ulmus parvifolia L.; Platycladus orientalis (L.) Franco), shrub species (Rosa chinensis Jacq.; Yucca filamentosa L.), and herbaceous species (Cynodon dactylon L.; Salsola sp.; Coreopsis lanceolata L.; Lolium perenne L.; Setaria viridis (L.) P. Beauv) exhibit significant dominance. The study reveals a high level of complexity but a low potential in the structure of urban flora biodiversity, indicating weak resilience, adaptation, and regeneration capability.
These results suggest that the fundamental principles governing natural biodiversity transformations�lack of identity, unified logic, harmony, purpose, and order�are disrupted within urban ecosystems due to the introduction of subjective logic, harmony, goal orientation, and order
\u27Discrete Maximum Principle Honored by Conventional Finite Volume Schemes for Diffusion-Convection-Reaction Problems: Proof with Geometrical Arguments
No full textFrom the Engineering point of view, the Maximum Principle is physically an important property met by solutions of elliptic partial differential equations (PDE for short) of second order governing diffusion-convectionreaction phenomena. This property is also called Positivity-Preserving Property in the literature. At the discrete level the Positivity-Preserving Property is required for any numerical scheme designed for solving such PDE. By means of algebraic arguments it is well-known that conventional finite volume schemes for second order elliptic PDE meet the discrete maximum principle. In this communication we expose a new technique based upon geometric arguments for proving that conventional finite volume schemes for diffusion-convection-reaction problems meet the discrete version of Maximum Principle. Notice that the above mentioned geometrical technique works for any space dimension
Perceptions of Climate Change: How Social Dynamics Shape Environmental Decision-Making
