introduction soil is one of the most valuable national resources that can be wasted by erosion phenomenon. therefore, prevention of soil erosion is universally considered. erosion is a process by which soil particles are separated from their original context and can be moved to another location. rill erosion is a kind of water erosion in which detachment and movement of soil particles can be af...

The effect of seedling age and number per hill on yield contributing characters Transplant Aman rice in Khulna region was investigated from July to December 2002.The treatments included the experiment consisted 4 (viz.15, 25, 35 45 day old seedling) 5 hill-1 (viz. 1, 2, 3, 5). It found that 25 produced tallest plant (118.87 cm), highest total tiller (33.02), effective (30.37), longest panicle l...

The influence of topography on sonic boom propagation is investigated. full two-dimensional Euler equations in curvilinear coordinates are solved using high-order finite-difference time-domain techniques. Simple ground profiles, corresponding to a terrain depression, hill, and sinusoidal terrain, examined for two waves: classical N-wave low-boom. Ground reflection the affected by elevation vari...

Background and objectives: Diabetes is a metabolic disease with hyperglycemia, decrease in insulin secretion or de-sensitization of peripheral cells to insulin.Onosmadichroanthum is a species of Boraginaceae and is used in traditional medicine for its anti-oxidant, anti-inflammatory and antibiotic properties, however data on its anti-diabetic effects ...

Variegate porphyria (VP) is characterized by photocutaneous lesions and acute neuropsychiatric attacks. Decreased protoporphyrinogen oxidase activity results in accumulation of protoporphyrin (ogen) IX and coproporphyrin (ogen) III. During acute attacks delta-aminolevulinic acid and porphobilinogen also increase, suggesting that porphobilinogen deaminase (PBG-D) may be rate limiting. We have ex...

Lianas are predicted to perform better than trees during seasonal drought among tropical forests, which has substantial implications for tree and forest dynamics. Here, we use whole-plant trait comparison test whether lianas allocated on the resource acquisitive end of continuum woody plant strategies. We measured morphological biomass allocation traits seedlings 153 species occurring in a Thai...

Let us consider the Dirac operator L = iJ d dx + U, J = ( 1 0 0 −1 ) , U = ( 0 a cos 2πx a cos 2πx 0 ) , where a 6= 0 is real, on I = [0, 1] with boundary conditions bc = Per, i.e., F (1) = F (0), and bc = Per−, i.e., F (1) = −F (0), F = ( f1 f2 ) ∈ H(I). Then σ(Lbc) = −σ(Lbc), and all λ ∈ σPer+(L(U)) are of multiplicity 2, while λ ∈ σPer−(L(U)) are simple (Thm 15). This is an analogue of E. L....

OBJECTIVES A recent editorial in Medicine and Science in Sports and Exercise concludes that the study of Hawkins and colleagues confirms "beyond any doubt the proposition of Hill and Lupton". It is not clear which of Hill and Lupton's propositions have been proved "beyond any doubt". METHODS A review of all the relevant publications of A V Hill and his colleagues. RESULTS Hill and Lupton be...
