Abstract:

In acid-base titrations, indicators are used to show sharp color change at intervals of pH. Natural pigments in plants are highly colored substances and may show color change with variation of pH. An attempt has been made to investigate the indicator activity of flower pigments and to replace synthetic indicators as they have certain disadvantage like chemical pollution, availability problems and high cost.

Abstract:

This paper studies the vibrational characteristics of multi-span beams with continuously varying rectangular cross-section of depth and breadth proportional to Xs and Xt respectively where s and t may be given arbitrary real numbers for a truncated beam and arbitrary positive numbers for a sharp ended beam and x is the coordinate along the centreline of the beam, measured from the sharp end of the beam. The Bernoulli-Euler theory of bending is used to describe the dynamic deflection of the beam. A new set of admissible functions are developed from the static solutions of the tapered beam with

Abstract:

Expecting ambulance clinicians to dependably differentiate the life-threatening organ dysfunction caused by sepsis from an inflammatory response to a non-infectious aetiology, relying upon vital signs and a physical examination of the patient alone, must be considered unrealistic. Although lactate measurement has been integrated into numerous prehospital sepsis screening tools, it is not yet measured routinely within UK ambulance services. Research has generally focused on whether handheld point-of-care lactate measurement devices are as accurate as laboratory analysis of venous or arterial sa

AbstractGeneral three-point quadrature formulas for the approximate evaluation of an integral of a function f over [0,1], through the values f(x), f(1/2), f(1−x), f′(0) and f′(1), are derived via the extended Euler formula. Such quadratures are sometimes called “corrected” or “quadratures with end corrections” and have a higher accuracy than the adjoint classical formulas, which only include the values f(x), f(1/2) and f(1−x) . The Gauss three-point, corrected Simpson, corrected dual Simpson, corrected Maclaurin and corrected Gauss two-point formulas are recaptured as special cases. Finally, s

The alkalinity of water is one of the important parameters of water quality. The volumetric titration method using a standardized hydrochloric acid solution is a prevalent technique to estimate individual concentrations of basic radicals, like, , , and ions, which are primarily responsible for the alkalinity of water. However, the method needs two external indicators, namely phenolphthalein and methyl red to mark the end points of titrations. Furthermore, accuracy of the method is sacrificed due to inevitable parallax errors during marking of the end point of titration. This present work repor

Abstract. Portable laser scanners, handheld and mobile, have gained popularity for their ability to rapidly and economically document scenes. However, the acquired data are characterized by hight levels of noise and by low resolution, both affecting their consequent analysis and 3D modeling. It is customary to enhance their quality by denoising the data by means of point position updates where current approaches independently predict the displacement per point. Such strategies neglect local structural consistency and often yield a non-smooth outcome. To address these shortcomings this paper fo

The aim of the experiments was to see which of the various Clactonian tool types could best reproduce the sharp, straight-sided taper of the Clacton spear point. Because of the hardness of the wood the experimenter was forced to begin close to the end of the wooden staves. The unretouched flakes when used in an outward whittling motion tended to produce point profiles with rounded tips; these resemble the point of the Lehringen lance. The Clactonian notch

Although synchrotron radiation is thought to be well understood in a theoretical sense, the practicalities of controlling a synchrotron source sometimes seem difficult. Often the output spectrum contains sharp peaks, especially at the high-frequency end of the spectrum. These spikes are unwanted because they rob power from desired frequency intervals, and unexpected because idealized theory predicts a quite smooth spectrum. In the face of such difficulties, it has been natural to suspect some sort of engineering shortfall. But the present paper argues that the spectral structure may point inst

The physical nature of the sharp yield point is established: the drop in the load after reaching the (upper) yield limit occurs as a result of dislocations being an extraction out of the cloud of the embedded atoms and vacancies (Cottrell's cloud).

The algorithm firstly defines the concept of end line which through the core of the circular template, and analyses the number of end lines in the corner point, thus obtains an initial response function of the corner. Then puts forward a non-maxima suppression method by defining the concept of uniformity coefficient of the non-end line. Finally, compared with existing algorithms, experiments indicates that the improved algorithm has the fast and accurate advantages. I.IntroductionCorner detection

Abstract:

Within the framework of the presented scientific work, from a medical and legal point of view, studies on human stem cells are considered, which are aimed at creating a new human-like creature from them. The concept of «stem cells» is analyzed, as well as their main types. As a practical component of the article, the work of research scientists who were able to derive an embryo-like creature from human stem cells is presented. The question of the problematic nature of this kind of research is raised both for modern bioethics and for humanity as a whole. At the end of the work, recommendatory c

Abstract:

The spatial resolution of magnetic resonance imaging (MRI) is often limited due to several reasons, including a short data acquisition time. Several advanced interpolation-based image upsampling algorithms have been developed to increase the resolution of MR images. These methods estimate the voxel intensity in a high-resolution (HR) image by a weighted combination of voxels in the original low-resolution (LR) MR image. As these methods fall into the zero-order point estimation framework, they only include a local constant approximation of the image voxel and hence cannot fully represent the u

Abstract:

The Hp-Cloud meshless method was developed to study the dynamic analysis of arbitrarily shaped thin plates with intermediate point supports. By proposing a special pattern for the influence radius of nodes and a polynomial type of enrichment function, the Hp-Cloud shape functions with Kronecker delta property were constructed. They can satisfy the zero deflection conditions for the field nodes at the point supports. The results obtained from these shape functions agree well with the previous ones, showing good accuracy and convergence. For plates with sharp corners, it is not possible to const

Abstract Structure-selective endonucleases cleave branched DNA substrates. Slx1 is unique among structure-selective nucleases because it can cleave all branched DNA structures at multiple sites near the branch point. The mechanism behind this broad range of activity is unknown. The present study structurally and biochemically investigated fungal Slx1 to define a new protein interface that binds the non-cleaved arm of branched DNAs. The DNA arm bound at this new site was positioned at a sharp angle relative to the arm that was modeled to interact with the active site, implying that Slx1 uses DN

Abstract Max Scheler and Siegfried Kracauer met during World War I and remained in correspondence until the early phase of the Weimar Republic. The two exchanged ideas and plans, and at times Kracauer sent his early essays for Scheler’s comments on and recommendations for publishing them. The correspondence brings to light some revealing philosophical similarities between the two authors: both Scheler and Kracauer were interested in material phenomenology, the philosophy of emotions, formal sociology; moreover, they also enthusiastically supported the German war.

The core of Ganymede is suggested to be mainly Fe but with a significant proportion of S. Effects of S as a core constituent are freezing-point depression, allowing for a molten core at relatively low core temperatures, and modification of transport properties that can influence the dynamo and thermal evolution. The electrical resistivity of solid and liquid Fe-FeS (~24–30 wt.% S) was measured up to 5 GPa and thermal conductivity was calculated using the Wiedemann–Franz law. These first well-constrained experimental data on near eutectic Fe-FeS compositions showed intermediate values of electr

Thin-walled structures are widely used in aeronautical and aerospace engineering. Conical and cylindrical shells structures, under axial compression, are prone to failure by buckling and typically show a snap-back phenomenon in the end-shortening curve. Path-following technologies based on Newton-type methods have difficulties to trace reliably the snap-back response due to the extremely sharp turning angle near the limit point. In this paper, a Koiter’s reduction finite element method, termed the Koiter–Newton (KN) method, is presented to trace reliably the post-buckling path of cylinders and
