Abstract: The genus Rosa (Rosaceae) encompasses approximately 150-200 species globally, with significant morphological diversity influenced by environmental conditions. High-altitude mountain ecosystems of the Himalayan region harbor unique rose populations adapted to extreme climatic conditions yet remain poorly documented. This study conducted a comprehensive morphometric analysis of wild rose (Rosa spp.) populations in Yasin Valley, Gilgit-Baltistan (2,547 m elevation), to quantify floral variation and establish baseline morphological data for this under-studied region. Ten rose specimens were collected from different locations within Yasin Valley (36.3334°N, 73.3572°E) during the flowering season (May-August 2024). Detailed measurements were recorded for five floral components: petals (n=9 per flower), sepals (n=4), leaves (n=4), stamen (n=4), and carpels (n=4). Length, width, and area calculations were performed using digital calipers (precision ±0.01 mm). Morphometric analysis revealed substantial intra-specific variation. Petal measurements showed mean length 2.86 ± 0.15 cm (R²=0.0073) and mean width 2.71 ± 0.12 cm (R²=0.01). Sepal dimensions averaged 1.53 ± 0.08 cm in length (R²=0.1291) and 0.76 ± 0.05 cm in width (R²=0.676). Leaf measurements recorded mean length 3.50 ± 0.18 cm (R²=0.1598) and width 2.21 ± 0.14 cm (R²=0.1441). Stamen length averaged 0.074 ± 0.006 cm (R²=0.1291) with width 0.30 ± 0.03 cm (R²=0.2727). Carpel measurements showed length 1.51 ± 0.09 cm (R²=0.0183) and width 1.20 ± 0.07 cm (R²=0.0016). This study provides the first quantitative morphometric dataset for rose populations in Yasin Valley. The observed variation suggests potential local adaptation to high-altitude conditions. These baseline data are critical for future biodiversity assessments, conservation planning, and understanding climate change impacts on alpine flora in Gilgit-Baltistan.

Abstract: The release of synthetic dyes, such as methylene blue (MB), into waterbodies poses significant environmental and health risks due to their toxicity, mutagenicity and persistence. Conventional water treatment methods often struggle to effectively remove these pollutants. However, biomass-derive adsorbent, like biochar, have potentials in removing dyes from polluted water efficiently at low cost. This study investigated the use of magnetic impregnated biochar of Pentaclethra macrophylla (African oil bean) seed shell (F_e-BC PM) as an adsorbent to remove MB by employing batch adsorption experimental set-up. The adsorbent was characterized by Fourier Transform Infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and Brunauer Emmett Teller (BET) for surface area and pore size analysis. Experimental adsorption data were modeled with such isotherm models as Langmuir, Freundlich, Temkin and Dubinin-Radushkevich. Langmuir Isotherm best fitted the adsorption process indicating monolayer adsorption and a monolayer adsorption capacity calculated, q_m was 29.07 mg/g. Four adsorption kinetic models were experimented (Lagergren pseudo-first-order, Ho and Mckay Pseudo-second-order, intraparticle diffusion and Elovich). Pseudo-second-order (PSO) best fitted the adsorption process, using the regression coefficient (R²) values obtained as basis. This indicated that the rate-limiting step of the adsorption process was chemisorption. The thermodynamic parameters suggest exothermic nature, increased randomness or disordering and spontaneity of the adsorption of MB onto F_e-BC at 30 ^oC, 35 ^oC, 40 ^oC, 45 ^oC, and 50 ^oC. The experimental results showed that high pH favoured the adsorption of MB onto magnetic impregnated biochar (Fe-BC) of Pentaclethra macrophylla seed shell. The FTIR spectral analysis indicated the presence of – OH of carboxylic acid, C-O of alcohol and C-Cl of alkyl halide all of which were functional groups identified on the Fe-BC surface.

Abstract. This article addresses the study of suspended sediment flow and the assessment of soil washout intensity from the mountain river basins of the Chirchiq–Ohangaron region. Data on suspended sediment runoff from rivers were used as the primary source material. The study also evaluates the contributions of seasonal atmospheric precipitation and air temperature to the formation of suspended sediment runoff in mountain rivers. Calculation nomograms are proposed for the quantitative assessment of suspended sediment runoff, developed on the basis of normalized regression equations that describe the relationship between suspended sediment runoff and hydrometeorological factors. The quantitative indicators of hydrological variables characterizing the intensity of soil washout from river basins have been refined through testing of the calculation nomograms. Furthermore, the long-term average values of suspended sediment runoff have been determined, including sediment volume norms, flushing modulus, erosion meter and other related parameters.

Abstract: There are two books in history. The first book is Gauss book < Disquisitions of Arithmetic > published in 1801. Contents are congruent and law of quadratic reciprocity. The second book is Jiang book < Foundations of Santilli isonumber theory with applications to new cryptgrams, Fermat theorem and Goldbach conjecture > Inter.Acad.Press, America-Europe-Asia (2002) (available in the PDF also http://www.i-b-r.org/docs/jiang.pdf). The Contents are Santilli isonumber theory, Jiang function Jn (w), complex trigonometric functions and complex hyperbolic functions. These two number theory books are the summary of the authors own independent research results. These results were not invented by the author in the past and laid the foundation for number theory. Jiang Book Exceeds Gauss Book.
