In this paper, the application of the second law of thermodynamics to boundary layer flow over a stretching surface with the presence of slip boundary condition and nanoparticles fractions is investigated. The model applied for the nanofluid incorporates the effects of Brownian motion as well as thermophoresis. A similarity solution is proposed. The solution depends on the Lewis number Le, Prandtl number Pr, slip factor b, suction/injection parameter λ, Brownian motion number Nt and thermophoresis number Nt. The effects of these six parameters on velocity, concentration and temperature profiles are discussed. The influence of the same parameters, the Reynolds number and the dimensionless group parameter on the entropy generation is also studied. It was found that the entropy generation was strongly impacted by these parameters.
The “upper unit” micaschists of the Edough Massif have undergone a low to moderate degree of metamorphism. The studied micaschists are composed of two distinct groups of rocks that are characterized by a typical metamorphic mineralogy. A first group comprises only weakly foliated garnet micaschists. The second group, located near the first, lacks garnet but contains large amounts of andalusite blasts. This obvious change in mineralogy indicates mobility of matter. This mobility is documented by evaluating the transfer using chemical and mineralogical variations in successive petrographic rock samples. In the micaschists of the Edough Massif, the transition from garnet micaschists to andalusite micaschists is not due to local changes of thermobarometric conditions. All rocks suffered the same P-T conditions. Neither can the mineralogical change be attributed to alteration. The variation of the chemical alteration Index (CIA) is not significant. The mineralogical changes thus are attributed to circulation of fluids that were freed during deformation.
Urban green spaces are integral to enhancing biodiversity and providing essential ecosystem services in metropolitan areas. This study examines the role of various types of urban green spaces, such as parks, community gardens, and green roofs, in supporting plant and animal species diversity. Additionally, the research evaluates how these spaces contribute to improved air quality, temperature regulation, and human well-being. By analyzing case studies from different global cities, the study offers insights into the design and management of urban green spaces to maximize their ecological and social benefits.
This study examines the impact of climate variability on the growth patterns of alpine flora in the European Alps. Through a combination of field observations and remote sensing data, we identified significant changes in flowering times and plant distribution over the past decade. Our findings suggest that temperature fluctuations and altered precipitation patterns are critical drivers of these changes. The study highlights the need for conservation strategies that account for the dynamic nature of alpine ecosystems in the face of climate change.
This paper is done to suggest a much more reliable method to forecast earnings using of data mining. Most studies in this area of research are based on the statistical and econometric models, which might encounter difficulties when dealing with the nonlinearity of financial data. Although data mining has already proved to be successful in many business applications, little research has been done on integrating financial statements' analysis with its techniques. This study utilizes Multi-layer Perception (MLP) and Radial Basis Function (RBF) techniques. In this way, it examines eight features of income statement of companies listed in Tehran Stock Exchange from 2020 to 2025. The results shows that MLP and RBF approaches respectively demonstrate about 96% and 98% efficiency of classification rate .
The study aims to assess the chemical composition, hypoglycemic effect, and antioxidant activity of Coriandrum sativum essential oil, focusing on its impact on glutathione peroxidase and antidiabetic effects on the pancreas and kidney in streptozotocin-induced diabetic rats. Thirty male albino rats were divided into three groups, with diabetes induced in two. Coriandrum sativum essential oil was analyzed using gas chromatography and administered to one group (40 mg/kg b.w. orally) for 21 days according to its LD50. Serum glucose and glutathione levels were measured, and histological examination of the kidney and pancreas was conducted. Results indicated that the major components of coriander oil are linalool (40.9%), geranyl acetate (12.8%), and γ-terpinene (10.6%). In the diabetic group, coriander essential oil significantly reduced serum glucose from 162.5±3.19 mg/dl to 72.96±1.73 mg/dl (p<0.05) and increased glutathione peroxidase levels from 59.72±2.78 u/g Hb to 124.83±2.31 u/g Hb (p<0.05). The kidney and pancreas of diabetic rats treated with coriander showed protective effects against diabetic pathological changes. The findings confirm the hypoglycemic and antioxidant activity of Coriandrum sativum L. oil, suggesting synergistic action of its bioactive compounds in improving diabetic conditions.
Urbanization poses significant challenges to biodiversity conservation, necessitating innovative strategies to mitigate its impacts. This study compares biodiversity conservation methods between Kuala Lumpur, Malaysia, and Manchester, United Kingdom, focusing on green infrastructure and policy frameworks. Through comprehensive analysis of urban planning documents, site visits, and interviews with local environmental agencies, we explore the effectiveness of implemented strategies. Our findings reveal that while both cities employ green corridors and community engagement initiatives, their approaches differ significantly in terms of policy integration and public-private partnerships. The study highlights the importance of adaptive management in fostering urban biodiversity, providing insights into potential enhancements for both Malaysian and UK urban conservation efforts.
