The perovskite structure has shown enormous utility in many facets of science in the past 50 years. From applications in high-temperature superconductors to piezoelectric sensors, the perovskite structure has been used in a wide array of cutting-edge areas of solid-state physics and materials science. LaTiO3 has a perovskite type crystal structure. It undergoes three phase transitions. At 50-100 K LaTiO3 undergoes a magnetic phase transition. John –Teller phase transition occurs between 100 K and 300 K. Also, insulator-metal (I-M) transition occurred at 500-550k. On the other hand, YtiO3 also have perovskite type crystal structure. It undergoes I-M phase transition around 750 K. We are interested to know the effect of the electrical and dielectric properties by replacing La with Y (Yttrium). To investigate the electrical and dielectric properties of La1-xYxTiO3 [x = 0.0, 0.2, 0.3 0.4 and 0.6] system, samples have been prepared by solid state reaction method. To confirm the crystal structure, room temperature X-ray diffractions were performed and no extra pack was observed. The measurement of frequency dependence dielectric constant shows that the decreases in dielectric constant observed with increase in frequency and the value of dielectric constant increase with increasing concentration of Y (Yttrium). We also observed that loss tangent decrease with increasing frequency and increase in concentration of Y (Yttrium) results to decrease in the value of loss tangent. The cole-cole plot shows that the grain size decrease with increasing concentration of Y (Yttrium), as a result resistivity decrease while conductivity increases with increasing concentration of Y (Yttrium).
在过去的 50 年中，包晶结构在科学的许多方面都显示出巨大的用途。从高温超导体到压电传感器，透辉石结构被广泛应用于固体物理和材料科学的前沿领域。LaTiO3 具有包晶型晶体结构。它经历了三次相变。在 50-100 K 时，LaTiO3 会发生磁性相变。约翰-泰勒相变发生在 100 K 到 300 K 之间，绝缘体-金属（I-M）相变发生在 500-550 K 之间。另一方面，YtiO3 也具有包晶型晶体结构。我们有兴趣了解用 Y（钇）取代 La 对电气和介电性质的影响。为了研究 La1-xYxTiO3 [x = 0.0、0.2、0.3 0.4 和 0.6] 体系的电学和介电性能，我们采用固态反应法制备了样品。为了确认晶体结构，进行了室温 X 射线衍射，没有观察到额外的包。频率相关介电常数的测量结果表明，介电常数随频率的增加而降低，介电常数值随钇（Y）浓度的增加而增加。我们还观察到，损耗正切随频率增加而减小，钇浓度增加导致损耗正切值减小。科尔-科尔图显示，晶粒尺寸随钇（钇）浓度的增加而减小，因此电阻率随钇（钇）浓度的增加而减小，而电导率随钇（钇）浓度的增加而增大。

In language and communication, multimodality refers to using various modes of signification to convey meaning. These modes transcend language to engage with audiences at multiple sensory levels. Over time, communication has evolved to reflect a paradigm shift towards a multimodal perspective. This leads to a complex interplay between different modes of shaping interpretations and constructing meaning in discourse, which has attracted little research. This paper explores the concept of multimodality as used in the television advertisement discourse of Raha premium maize meal, using the Multimodal Discourse Analysis Theory. The objective is to investigate how viewers interpret and perceive different modes of signification employed in the advertisement. A descriptive research design with a qualitative approach is used in the collection and analysis of data. The findings reveal that each mode of signification has a unique role, some of which television viewers hardly denote their meaning. Further, politics, religion, and culture influence the perception of some modes of signification used in the advertisement. We recommend that the advertisements be tailored with modes of signification that resonate with the expectations of television viewers. The findings of this paper are intended to enrich linguistic theory concerning the analysis of the representation of meaning in a text and perceptions of modes of signification used.

In the world of start-ups, private companies with a valuation exceeding $1bn are called “unicorns.” The term was initially meant to symbolize the uniqueness and remarkable growth trend of these highly valued businesses. Furthermore, unicorns have evolved into representatives of creativity and economic vitality, driving the development of new technologies, the creation of jobs, and the generating of money within their ecosystems. This worldwide trend is reflected in the emerging startup culture in India, which has seen an incredible rise in the country in recent years. Notably, startups like Khan Academy, and BYJU have reached multi-billion revenues in the previous years. The ventures are not just profitable but they offer many opportunities and encourage creativity through the use of advanced apps and technology. This has helped the country to become the third largest global home to unicorns after China and America. Using the data collected between 2020 and 2021, this study seeks to explain why these start-ups were so successful. Moreover, this paper analyzes the latest funding, valuations, and comparison of profit and losses for various unicorn companies in different sectors by utilizing several chart visualizations and showing multiple factors contributing to their success. Furthermore, with this comprehensive analysis of unicorns’ financial characteristics and performance measures, this paper will offer insightful information on their sustainability and obstacles to maintaining their unicorn status and for the new startups to rise in this changing and dynamic industry.

Rising incidence related to gluten illness, have gained significant attention and more demand for gluten free diet. This upsurge can be traced not only from the population that suffered from gluten–related disorders but also people who prioritize healthy lifestyles and practicing gluten free diets. The availability of gluten-free bakery products has increased dramatically in the last five years. Typically, conventional wheat products like pastas, breads, crackers and baked goods contain gluten. Nevertheless, numerous gluten-free alternatives exist, utilizing different flours and grains. However, developing an innovative gluten free product with highly acceptable sensory properties is the most challenging task. In addition to its nutritional advantages over regular wheat flour, gluten-free flours have higher levels of protein, fiber, vitamins and minerals. This can lead to bakery products having reduced levels of harmful fats, refined carbohydrates and sugars, making them a better choice for people trying to adopt a diet with a healthy lifestyle. Those who have celiac disease or gluten sensitivity can find a safe substitute that doesn't cause side effects of gluten. Diverse dietary preferences are catered by the bakery industry's increasing awareness of accessibility to gluten- free choices. The size of the market for gluten-free baking offers potential for innovation, technological improvement and adaptation to shifting consumer preferences. Hence, incorporating a range of gluten-free flours into a diet can enhance dietary diversity, which is beneficial for nutrition and overall health. This article reviews the use of gluten free flours in baking.

Female infertility, which results in disruption of the female reproductive function has link to indiscriminate or chronic burning of Mosquito coil (MC) culminating in increased levels of oxidative stress biomarkers. Oils with significant antioxidant effects have shown promising attenuating effects on oxidative stress processes in reproductive function. The study investigates the mitigative role of red-palm oil (RPO) on oxidative and antioxidant activities following exposure to mosquito coil smoke in female Wistar rats. The study employed 60 female rats of 160-200 grams and was randomly place into 5 groups. Group A was exposed to environmental air only, group B received 2ml of red-palm oil only, groups C was exposed to mosquito coil for 2-hours, groups D exposed to 4-hours of mosquito coil smoke and group E was treated with 2 ml of red-palm oil and 4-hours of mosquito coil smoke for 21-days. Data obtained was analysed using Graph pad prism 9.5 using ANOVA followed by post-Hoc Turkey comparison, and alpha was set at p≤0.05. Rats exposed to MC resulted in a significant increase in MDA levels, significant decrease in SOD, CAT, and GSH levels in exposed groups C and D compared to A. Treatment with RPO significantly reduced the levels of MDA in groups B and E as compared to D. Conversely, SOD and GSH showed a significant increase levels following RPO in groups B and E compared to D; and CAT had no significant difference in treatment groups B and E following RPO intake. Thus, the study concludes that RPO has an ameliorative effect by mitigating the effect of lipid peroxidation of MC exposed rats.
女性不孕会导致女性生殖功能紊乱，这与滥用或长期焚烧蚊香（MC）导致氧化应激生物标志物水平升高有关。具有明显抗氧化作用的精油对生殖功能中的氧化应激过程有很好的抑制作用。本研究调查了红棕榈油（RPO）对雌性 Wistar 大鼠暴露于蚊香烟雾后的氧化和抗氧化活动的缓解作用。研究使用了 60 只体重为 160-200 克的雌性大鼠，并将其随机分为 5 组。A 组只暴露在环境空气中，B 组只接受 2 毫升红棕榈油，C 组暴露在蚊香中 2 小时，D 组暴露在 4 小时的蚊香烟雾中，E 组在 21 天内接受 2 毫升红棕榈油和 4 小时蚊香烟雾的治疗。所得数据使用 Graph pad prism 9.5 进行分析，采用方差分析，然后进行土耳其事后比较，α 设定为 p≤0.05。与 A 组相比，暴露于 MC 的 C 组和 D 组大鼠的 MDA 水平显著升高，SOD、CAT 和 GSH 水平显著降低。因此，该研究得出结论，RPO 具有缓解 MC 暴露大鼠脂质过氧化反应的作用。

Oils with significant antioxidant effects have shown promising attenuating effects on oxidative stress processes in reproductive function. The study investigates the mitigative role of red-palm oil (RPO) on oxidative and antioxidant activities following exposure to mosquito coil smoke in female Wistar rats. The study employed 60 female rats of 160-200 grams and was randomly place into 5 groups. Group A was exposed to environmental air only, group B received 2ml of red-palm oil only, groups C was exposed to mosquito coil for 2-hours, groups D exposed to 4-hours of mosquito coil smoke and group E was treated with 2 ml of red-palm oil and 4-hours of mosquito coil smoke for 21-days. Data obtained was analysed using Graph pad prism 9.5 using ANOVA followed by post-Hoc Turkey comparison, and alpha was set at p≤0.05. Rats exposed to MC resulted in a significant increase in MDA levels, significant decrease in SOD, CAT, and GSH levels in exposed groups C and D compared to A. Treatment with RPO significantly reduced the levels of MDA in groups B and E as compared to D. Conversely, SOD and GSH showed a significant increase levels following RPO in groups B and E compared to D; and CAT had no significant difference in treatment groups B and E following RPO intake.

In 1959, Robert Noyce's invention of the first monolithic integrated circuit chip revolutionized the electronics industry, leading to an explosion of new electronics devices for human convenience. However, this digital revolution, coupled with scientific and technological advancements, has also given rise to a pressing issue: electronic waste, or E-Waste. The United Nations Institute of Training and Research (UNITAR) warn that global E-Waste is accumulating at a rate five times faster than it is being recycled. In 2022 alone, a staggering 62 million tons of E-Waste were produced worldwide. E-waste is laden with toxic materials such as lead, beryllium, cadmium, and many other toxic materials, posing significant threats to both human health and the environment. Improper disposal of E-Waste can contaminate soil and groundwater, exacerbating these hazards. To mitigate these risks, it is imperative to manage E-Waste judiciously and in an environmentally friendly manner. In India, the Ministry of Environment, Forest and Climate Change has established the E-Waste Management Rules of 2022 to regulate E-Waste management practices. The primary objective of this paper is to raise awareness about the importance of responsibly managing E-Waste to safeguard human health and preserve the environment. Effective management practices are essential to address the health hazards and environmental consequences associated with toxic materials in E-Waste.
